Hi
This is a very broad question on: 'what makes someone a successful entrepreneur?' and 'how to raise seed funding?'
Entire books have been written on how this is done, so any attempt to give you a professional answer in just a few lines would be unprofessional. Nevertheless, I will say that there are numerous factors that affect an entrepreneurs ability to raise early stage funding, among them are (in order of importance):
1. The team (how long they've been together, their skills, their past experience, their passion)/
2. existing customers / practical market research: how many existing users/clients are there. If your product/service doesn't exist yet, then how many people showed that they would buy the product/pay for the service (you can check this without actually having the product/service). this information is very important to investors (just throwing out potential numbers doesn't cut it).
3. The idea - yes, the idea only comes 3rd, as in most cases you will pivot (change the idea) at least once or twice before reaching the final version of the product/service.
4. Your connections / the amount of investors you approach.
5. Timing / luck.
If you give me more specific information (such as the type of product/service, the market, the team etc..basically your 'deck'), I will be happy to try advise you on the best way to raise money. For example, for a product, you should try avoid crowdfunding platforms unless you already have the entire manufacturing process and selling/shipping process ready. If not, you will be seeing 'fake'/copied versions of your product even before you hit the market.
Good luck
